Oh, what a lovely question! The sundial has been around for thousands of years, with some of the earliest known sundials dating back to ancient Egypt around 1500 BC. Isn't it fascinating how people have been using the sun's position to tell time for so long? It just goes to show the beauty and ingenuity of our ancestors.

The pin of a sundial is called a gnomon. It is the part of the sundial that casts a shadow onto the dial face to indicate the time.
The time needed for a sundial to move ten degrees depends on the specific location and time of year due to the changing position of the sun in the sky. Generally, it can take about 40-60 minutes for a sundial to move ten degrees.
